Invacare 3G Storm Series® 90 Part No 1143151
11.5 Using the Proper Batteries
1. Position battery on ground/flat surface as shown below.
2. Visually inspect the battery to ensure proper polarity:
The use of rubber gloves is recommended when working with batteries.
Invacare strongly recommends that battery installation and battery replacement ALWAYS be done by a qualified technician.
After ANY adjustments, repair or service and before use, make sure all attaching hardware is tightened securely -
otherwise injury or damage may result.
Unless otherwise indicated, make sure power to the wheelchair is OFF before performing these procedures.
Use 22NF or GP 24 batteries only. Failure to use the correct battery size and/or voltage may cause damage to your
wheelchair and give you unsatisfactory performance.
Use proper lifting techniques (lift with your legs) to avoid injury when lifting batteries.
• 22NF batteries weigh 37 pounds each.
• GP24 batteries weigh 51 pounds each.
ALWAYS use a battery lifting strap when lifting a battery. It is the most convenient method and assures that the battery
acid will not spill. It also helps to prolong the life of the battery.
DO NOT tip the batteries. Keep the batteries in an upright position.
When tightening the clamps, always use a box wrench. Pliers will “round off” the nuts. NEVER wiggle the battery
terminal(s)/post(s) when tightening. The battery may become damaged.
If there is battery acid in the bottom of the battery box or on the sides of the batteries, apply baking soda to these areas to
neutralize the battery acid. Before reinstalling the existing or new batteries, clean the baking soda from the battery tray or
batteries being sure to avoid contact with skin and eyes. Determine source of contamination. NEVER install/reinstall a
battery with a cracked or otherwise damaged case.
